Why "沒有發現密碼" message for BitLocker recovery?

Passware Kit shows "No password" or "Password not found" message in case no "Password" protection was set in BitLocker encryption. Mostly it means your BitLocker volume was encrypted with a Recovery Key which cannot be found with the brute-force method but only extracted from a memory image or hiberfil.sys.
